What is Low-E glass and what are its applications

  1. Low-E glass is an energy-efficient glass
  2. Low-E glass can make your home or building more comfortable
  3. There are two types of Low-E coatings

 

When it comes to glass, the type to be used for a given purpose is usually one of the last things people think about. Sure you have probably heard of bulletproof and tempered glass, but there is another type that is relatively unknown: Low-E glass. That being said, knowing what the nature of Low-E glass and its applications can be helpful when it comes to your endeavors that require the use of glass.

Before getting into the specific details and features of Low-E glass, it is important to first understand how sunlight works and how it can affect your home or any other building. Sunlight contains different forms of energy such as light and heat thanks to electromagnetic radiation. You can perceive some of this radiation within a spectrum as the light and colors you can see in a rainbow, but light also exists outside of that spectrum.

Other types of light that we can’t perceive but exist include infrared and ultraviolet light. Ultraviolet rays from the sun are what causes sunburns while you feel infrared radiation from sources of heat such as a fire, furnace, or oven. It is these three elements (visible light, infrared and ultraviolet) that Low-E glass and its applications are concerned with.

Now that you understand some of the basic concepts surrounding low-emissivity glass, the reason why it is considered to be an energy-efficient glass is that it minimizes the amount of infrared and ultraviolet light that passes through it, without affecting the amount of light that passes through.

This is thanks to an exceptionally thin layer of coating that is usually made from two or more layers of metal or metallic oxide. This is specifically made to block out unnecessary electromagnetic radiation. Low-E glass seeks to make any building have a consistent temperature by reflecting the interior temperature back inside while keeping ultraviolet and infrared rays out.

 

Low-E glass can make your home or building more comfortable

Since Low-E glass makes the temperature of buildings more consistent, a comfortable atmosphere is usually achieved when it is applied to windows and other openings that allow light to pass through. The most common window set-up is either a double or triple-glazed unit wherein two or more glass panes are separated by a spacer and a gas-filled space — argon, and krypton being the inert gas of choice. Gas is needed to prevent heat from escaping in air drafts.

Thanks to this kind of set-up, heat transfer is reduced and optimal thermal insulation is achieved — resulting in a more comfortable experience for the people inside the building regardless of whether it is sweltering or snowy outside.

 

There are two types of Low-E coatings

As mentioned above, low-emissivity glass relies on a thin coating of metal/metallic oxides to do the blocking of unwanted electromagnetic radiation. That being said, there are two kinds of Low-E coatings that you would do well to know.

 

Passive Low-E Coating

Passive Low-E coatings are made through the pyrolytic “hard-coat” process which produces a coating that is best used in very cold environments. The durable pyrolytic coating allows some of the sun’s short-wave infrared energy to pass through the glass, giving the building a form of “passive” natural heating. This helps you save money on electricity since you rely less on space heaters and other artificial heating methods.

 

Solar Control Low-E Coatings

If passive Low-E coating is made through the hard coat, pyrolytic process, then the solar control Low-E coating has the Magnetron Sputtering Vapor Deposition (MSVD) process. This coating, which is also called “soft-coat”, needs to be sealed in an insulated or laminated glass. What you’re getting with this coat when compared to the previous type of coating is superior resistance to the sun’s radiation.

It is for that exact reason why solar control Low-E is the preferred coating for cold to hot climates. Since it offers better UV and infrared protection it keeps buildings cooler and reduces air conditioning-related energy consumption.

 

Key Takeaway

If you are looking for a way to give your home or building better insulation and protection from the sun’s electromagnetic radiation, then Low-E glass can be a great option. With Low-E coating options available that are applicable for different climates, it is convenient regardless of your location.

When you’re trying to decide which window size, style, and design are best for your building, you should also consider the type of glass you are going to be using. Not only does Low-E glass provide practical use and protection, but it can also be a source of energy efficiency and savings.

How Shatterproof Glass is Made

How Shatterproof Glass Is Made

How is shatterproof glass made?

  1. The glass is cut to size, polished, and cleaned
  2. The glass is then further toughened
  3. Laminate interlayers are cut and applied to the glass
  4. The glass ‘sandwich’ is heated
  5. It is finally cleaned and trimmed

 

Shatterproof glass or laminated glass is one of the most used glass products in the world today. As a safety glass, it is used for a wide number of applications. You can commonly see it as automobile windshields, skylight glazing, curtain walls, and store windows. The reason for this is because when shatterproof glass is hit with a strong force, it doesn’t break into large, sharp pieces that can injure people. In fact, laminated glass will continue to stay in one piece even if it has been pierced or cracked multiple times.

Aside from its physical protection, it also protects people from harmful UV rays from the sun. Using the right materials during production can give it the potential to block 99.9% of all UV rays. Beyond its protective qualities, shatterproof glass is also good for sound insulation.

Having said all that, you may be curious as to how shatterproof glass is made. What makes it so averse to shattering and breaking? Continue reading because here is how shatterproof glass is made.

 

The initial glass is cut to size, polished, and cleaned

Laminated glass usually starts as normal sheets of glass that are cut to form a desired shape or size. This usually depends on a given client’s specifications or if it’s premade before selling, then a uniform rectangular shape is usually the go-to.  Once it is properly cut, the glass is polished and cleaned to ensure no impurities interfere with the whole process.

 

The glass is then further toughened

The Glass Is Then Further Toughened

After cleaning, the glass itself needs to be a bit tougher before undergoing the process that creates the shatterproof glass itself. To do that, it has to go through a process that involves minor heating and cooling that can be likened to ‘quenching’. Quenching makes the outer layer of the glass more compressed instead of remaining in tension. This process makes the glass a tad more resistant to breaking on its own.

 

Laminate interlayers are cut and applied to the glass

After quenching, an interlayer is cut and added per sheet. Interlayers, in this case, are elastomeric polymers such as EVA (Ethylene-vinyl acetate) or a strong binding resin such as PVB (Polyvinyl butyral) that is placed in between the glass during production. Using either material as an interlayer would allow the glass to remain bonded while broken — giving it the ‘shatterproof’ moniker.

After a couple of interlayers are added, the 2nd sheet of glass is placed on top, forming what seems like a glass ‘sandwich’. Consider this the shatterproof glass in its rawest form. The glass is held together using a mixture of clamps and tape.

 

The glass ‘sandwich’ is heated

In order to turn the raw glass sandwich into actual shatterproof glass, it has to be heated and compressed simultaneously. There are a number of ways to achieve this. One way to do this is by putting the glass through a ‘nip roller’. For bigger sheets of glass, another popular method involves putting the glass in a vacuum-sealed silicone bag then placed in an oven.

This process removes the air in-between the layers and allows the glass sheets to bond with the interlayer. It’s important to note here that this process is what produces that ‘spider web-like’ cracking pattern when shatterproof glass is cracked.

 

It is finally cleaned and trimmed

After the previous process of heating, what you’ll end up with is the final product. However, it still needs some touch-ups and quality control, which is why it has to be re-cleaned and trimmed. Cleaning in this sense pertains to wiping the surface and making sure that there are no blemishes that can be seen.

Trimming is done with a hot-knife tool to remove excess material from the sides of the glass. This is because of the processed interlayers that were heated, compressed, and eventually overflowed. After trimming, it is finally ready for use.

 

Key Takeaway

Understanding how shatterproof glass is made is important because it allows you to understand how the glass acquires the features it is known for. It also helps you know what kind of glass products are going to perfect for your purposes. Whether it’s for a new windshield or for hurricane-resistant glass, shatterproof or laminated glass could be the way to go.

  5. The different types of glass

 

All glass and aluminum suppliers in the Philippines will tell you that glass is being used in the building industry, whether it’s used to make conventional windows or structural members in new-age buildings. Glass is used in construction and for architectural purposes in engineering. With so many different properties and uses, you can definitely say that glass can be just as great as aluminum and steel. Here are some of the uses of glass as an ideal material for construction:

 

Traditional Form and Function

A glass is described as a transparent, sparkling, delicate, and illustrative material. It is one of the most useful and most interesting materials with more applications and installation techniques that are constantly in development. Glass is used in various methods during construction projects with an exact form and type.

The most familiar glass forms are fiberglass products that are being used for insulation and translucent panels, transparent blocks, and windows. Another is glass insulation, and it is typically installed as loose particles blown into cavities and ceilings used as specialized equipment.

 

Application Advancement

Application Advancement

Glass in its solid, float manufactured state really shines in construction and it is constantly being used in more and more construction projects. However, it requires more advanced installation methods. Prefabricated structural fiberglass panels make use of interlocks and adhesives in achieving engineering performance like of steel and wood elements. There are a lot of installation methods that have improved as well, such as frameless glazing utilizes specialized adhesives to hold glass panels against structural supports in place without an exposed framework. This leads to a smooth and continuous effect on a lot of buildings exteriors, floors, and facades.

 

Transparent Uses

The main property of glass is transparency which allows the vision of the outside world through it. The transparency of glass can either be from both sides or from one side only. In the recent forms of recent construction techniques, glass has always been utilized in making beams and columns.

It does not only look dramatic but also has an attractive compression and strength to weight ratio. Glass achieves its strength when loaded in compression. Post-tensioning techniques are used to ensure the structural elements of glass bear compressive loads.

 

Outlook

Outlook

The developments in the glass sector are not all limited to its classic properties, whether its energy savings and solar protection, but it can also improve and change its stability and surface. As the product versatility for glass increases, so does the need for architects, engineers, and building owners to consult with a glass protector.

 

Glass for Windows and Facades

The primary use for windows is to supply natural daylight, fresh air, and provide protection from rain, cold, and wind. These purposes which are characteristic for windows can be mostly achieved by means of special multifunctional designs.

Sophisticated window and facade systems combine different technical demands with the creative freedom of planning. The potential of glass is not only for increasing in transparency and quality of living, but it can also emphasize the vitality of reflecting surfaces and the presence of structures.

 

Types of Glass Used in Construction

Let’s discuss some of the different glasses that are broadly used for construction:

Soda Lime Glass

Soda Lime Glass or Float Glass is a mixture of sodium silicate and calcium silicate. It is smooth at low temperature and it can be blown or welded easily when infusion condition. It is colorless and it is mainly used for window panes and for the laboratory tubes and other apparatus.

Potash Lead Glass

A type of glass with a mixture of potassium silicate and lead silicate. Its properties possess bright luster and great refractive power. It is mostly used in the manufacturing of artificial gems, electric bulbs, and lenses.

Common Glass

A mixture of sodium, calcium, and iron silicate. It is brown, green, and yellow in color and mainly used for in manufacturing medicine bottles.

Shatterproof Glass

It is used for windows, skylights, floors etc. Some type of plastic polyvinyl butyral is added in the making process so it cannot form sharp-edged pieces when it breaks.

Double Glazed Units

This type of glass is made by providing an air gap between two glass panes in order to reduce heat loss and gain. Normal glass can cause an immense amount of heat gain and 30% of the loss of heat or air conditioning energy. Green, energy efficient glass can reduce this impact.

Special Glasses

Some properties of glasses can be suitably altered by changing basic ingredients and adding a few more ingredients. It is now emerged as a versatile material to meet any special requirement in engineering.

 

Key Takeaway

Most glass and aluminum suppliers in the Philippines will tell you that glass is a great material to use for construction purposes. With different types of glasses, transparent uses, and properties, glass is definitely a great material to use for buildings and other construction purposes.
